i can not get any of the libraries that get data from the Wi nunchuck to work on the DUE. does anyone have a library that works on the DUE or some suggestions as to how to use I2C to communicate with it?

found the basic wire code needed and can read the nunchuck but it is horribly slooooow and also gets garbage every second read. does anyone have experience with this and know if this is "normal" i have tried to find documentation on what the nunchuck wants for initialization and have found various suggestions but nothing works any better. here is s simple sketch that does not use a library. all the nunchuck functionality is in the sketch with wire function. i am connecting clock and data lines to pins 21 and 20 and using 3.3 volt power, not analog pin power.
